Abstract: A radar sensor includes a transmitter module, a receiver module, and a lens device. The transmitter module has a transmitter-side patch array antenna and transmits radar signals with a first directivity. The receiver module has a receiver-side patch array antenna and receives the radar signals reflected in the detection area. The lens device has a first lens for the transmitted radar signals and a second lens for the reflected radar signals. The second lens is arranged substantially directly adjacent to the first lens in a direction of a length extension in a top view. The first lens and the second lens are designed so that a ratio between the length extension and a width extension of the first directivity of the radar signals or a second directivity of the radar signals is influenceable, i.e., the radar signals with the first directivity are convertible into radar signals with the second directivity.

Abstract: A sensor device for determining a position of seeds while sowing. The sensor device includes a radiation assembly which generates an illumination radiation oriented towards a target area, and a detection assembly. The radiation assembly includes a radiation source which provides an emission spectrum of the illumination radiation covering a spectral range. The detection assembly includes a radiation detector which detects an incident radiation, and a filter member with an attenuation band and a pass band. The radiation detector includes a field of view. The pass band has an attenuation which is less than an attenuation of the attenuation band in a wavelength range where the wavelengths are longer than those of the attenuation band. The target area and the field of view intersect. The radiation source and the radiation detector form a triangulation arrangement so that a distance from the target area to the detection assembly can be determined.

Abstract: A sensor array includes a housing with a circumferential housing wall, which defines a housing opening, with a sensor circuit board with a high-frequency sensor. The sensor circuit board in the housing is arranged such that the high-frequency sensor is directed towards the housing opening. A one-piece closing cap closes the housing. The one-piece closing cap has a circumferential cap wall and a high-frequency lens. The high-frequency lens closes the circumferential cap wall on the front side and is directed towards the housing opening. A distance between the high-frequency lens and the high-frequency sensor and thus a focal length is predefined by a lateral length of the cap wall.

Abstract: A control device for controlling a height of a boom of a vehicle. The control device includes a transmission/receiver set, a processor, a control, and a communication interface. The transmission/receiver set transmits an initial measuring signal and receives an initial reflection signal in response thereto, and transmits a second measuring signal and receives a second reflection signal in response thereto. The processor determines a majority of initial reflection components of the initial reflection signal, a majority of second reflection components of the second reflection signal, and compares the initial reflection components with the second reflection components to determine matching reflection components. The matching reflection components indicate a layer of reflection objects. The communication interface links the processor with the control and to determine a control signal for controlling the boom based on the matching reflection components.
